Doctoring A Doctorate

I had to do with a clergyman last year, a doctor of psychology. But having a few modest qualifications myself in the field, a few things didn't add up. I obtained his qualifications. Nothing checked out -- beginning with the institution which conferred the degree. It was reported as "bogus" and "fake". That need not be fatal of course, but it does arrest one's attention. I approached his denomination: did he have the doctorate? They would not respond. Or rather, they referred me to their legal department. And that, I thought, would be a perfect waste of time.
